Planets $100 Mercury Planets $200 What are the inner planets in order from the sun? Planets $200 Mercury, Venus, Earth, and Mars Planets $300 What are the outer planets in order from the sun? Planets $300 Jupiter, Saturn, Uranus, Neptune, and Pluto. Planets $400 How is Pluto classified? Why? Planets $400 Pluto is classified as a dwarf planet because it is so small. Planets for $500 Why does a year on Jupiter last longer than a year on the Earth? Planets for $500 Jupiter is farther from the sun. The Sun for $100 What is the star at the center of our solar system called? The Sun for $100 The sun The Sun for $200 What force keeps the planets in orbit around the sun? The Sun for $200 Gravity The Sun for $300 What two gases mainly make up the sun? The Sun for $300 It is mostly composed of hydrogen and helium. The Sun for $400 What are sunspots? The Sun for $400 These are the dark areas that are cooler than the rest of the sun’s surface. The Sun for $500 Where does the process of nuclear fusion take place on the sun? The Sun for $500 Nuclear fusion takes place in the sun’s core. The Moon for $100 What are the different shapes the moon has in the sky called? The Moon for $100 Phases The Moon for $200 Why would the same object weigh more on the Earth than on the moon? The Moon for $200 The moon has less gravity than the Earth. The Moon for$300 What phase is the moon in when you can barely see it? The Moon for $300 It is the new moon. The Moon for $400 How long does it take the moon to revolve around the Earth? The Moon for $400 About 28 days. The Moon for $500 Why do we only see one side of the moon from the Earth? The Moon for $500 We only see one side of the moon because its revolution and its rotation take exactly the same amount of time. Weather for $100 What is the layer of air that surrounds the earth called? Weather for $100 The layer of air that surrounds the Earth is called the atmosphere. Weather for $200 What is weather? Weather for $200 Weather is the condition of the atmosphere outside at any given time. Weather for $300 What is the boundary line between two moving air masses called? Weather for $300 A front Weather for $400 What are the four forms of precipitation? Weather for $400 Rain, snow, sleet, and hail Weather for $500 What causes wind to form on the Earth’s surface? Weather for $500 Wind is caused by the uneven heating of the Earth’s surface by the sun. Water for $100 What is the water cycle? Water for $100 The change of water from one state to another as it moves between Earth’s surface and the atmosphere Water for $200 What is evaporation? Water for $200 Evaporation occurs when a liquid changes to a gas. Water for $300 What is precipitation? Water for $300 Precipitation is any form of water that falls naturally from the clouds. Water for $400 How does the sun affect the water cycle? Water for $400 The sun heats the water and causes it to evaporate. Water for $500 What is the process by which water vapor becomes liquid water? Water for $500 Condensation Grab Bag for $100 What is rotation? Grab Bag for $100 Rotation is the spinning of a planet or a moon on its axis. Grab Bag for $200 What is the path that a planet or moon takes as it moves around another object called? Grab Bag for $200 A revolution (or orbit) Grab Bag for $300 What is the lunar cycle? Grab Bag for $300 The changing phases of the moon as it revolves around the Earth Grab Bag for $400 What is refraction? Grab Bag for $400 Refraction is the bending of light as it moves from one material into another. Grab Bag for $500 What is a warm front? Grab Bag for $500 The boundary line formed when a warm air mass catches up to a cold air mass.
